Do not reencode fonts. By default, fonts
are reencoded to Unicode whenever possible.

-g n

Set the type of scalable
glyphs that we write. If n is 0, no scalable glyphs are written; this is
legal but confuses most current software. If n is 1, a single scalable
glyph (the undefined glyph) is written; this is recommended, but triggers
a bug in current versions of FreeType. If n is 2 (the default), a sufficiently
high number of blank glyphs are written, which works with FreeType but
increases file size.

-m n

Set the type of scalable metrics that we write.
If n is 0, no scalable metrics are written, which may or may not be legal.
If n is 1, full metrics for a single glyph are written, and only left sidebearing
values are written for the other glyphs. If n is 2, scalable metrics for
all glyphs are written, which increases file size and is not recommended.
The default is 1.
